Monitoring and Protection of Real Time Safeguard of Workers Exposed to Physical Agents in Construction Sites through Dynamic WSN

The foremost critical task for construction sites is of keeping track of workers spread out across a large construction areas .It becomes even difficult when construction site tunnels collapse. Many construction sites use a radio system to track workers, but when a collapse occurs, the base stations connected by a thin wire often are rendered useless. In this project to overcome the demerits of radio system we used wireless technology for tracking the workers. For this purpose a small RF transmitter module is equipped to each person entering a construction site. Each transceiver placed in the construction look after the location of workers. The transceivers communicate with base stations through Zigbee module. In addition of tracking the location of workers we also include sensors such as temperature & humidity to intimate the base station & workers when some atmosphere changes occur. Construction operators are now able to monitor the real-time locations of each worker to better pinpoint their locations in the event of an emergency. Even after a full-day of use, construction operators can locate an individual worker within ten feet.
